In CCI4 , all C-Cl bonds are _ but molecule is _ overall:

Explanation

In CCl4, all C-Cl bonds are polar, but the molecule is nonpolar overall.Each C-Cl bond in CCl4 is polar due to the difference in electronegativity between carbon (C) and chlorine (Cl). Chlorine is more electronegative than carbon, so it attracts the electrons in the bond more strongly, leading to a partial negative charge on the chlorine atom and a partial positive charge on the carbon atom.However, the molecule CCl4 has a tetrahedral geometry with four identical polar C-Cl bonds arranged symmetrically around the central carbon atom. The dipole moments of these polar bonds cancel each other out, resulting in a molecule with no net dipole moment. This cancellation of dipole moments makes the molecule nonpolar.
